Mvm m illllllllllll K "Toia ll 'whohi it i I t I Be it known that I, tALFRED G.-KILGEN, a citizen'of the United States, residingat. the

,panyingldrawings, forming part ofTthis city of St, Louis, State of Missouri, have invented a certainnew and useful Improvement in Organ-Valves,of: which the following is a 'full, clear, and exact description, such as will enable others skilled in the art to which it appertainsrto make and use the sameyreference being had tothe accom-:

specification. t r V p This invention relates broadly to pneumatic organs, andspecificallyto. certain improvements in the valve action and valve- 1 construction for such instruments.

The objectof my invention isto provide a valveconstruction which is very durable, in that the flexible portions are not subjected to strains or creasingwhich tend. to wear -out the vmaterial; to provide'a valve which is quick and certain in seating and unseating, dueto the, fact thatit is entirely free and unattached with respect to other parts; to providea valve which is entirely noiseless :inall operations; and to g provide a tvalve and valve action which may ibe-constructed or pointed out hereinafter,- reference being at lowcost, and repaired, necessary, with 3 but little trouble and expense. I r

Other and furthersobjects will beobvi'ous had to theaccompanying drawings, in which Figure 1 ,is a, transverse vertical section 1 through anillustrative Willd'ChBSiS and sound board containingmy inventionyand' showing thev valve in stopped position and Fig. 2is a similaryertical section show-" lngat-he valve'in open or playing position.

eferring totheseillustrations bythe reference numerals applied, "let it 'be 'underq stood'that represents generally" the wind chest, 2 the sound-board, and 4 a pipeh" The wind; chest and :sound board,'-: it will be understood, are of proper dimensions to su port .athe desired pipes, and the 1 wind chest isvarrang'edto be supplied withair under the chamber 5 is disposed .a'seating stripil7 pressure in 1 any suitable conventional fashion. aUnder eachiof the pipes there'is formedin the bottom :board of the wind chest a valve chamber-5; which isad'a'pted-to be. 1' supplied, 5 with fair through a channel 6,

which-is suitably'icontroll'ed by a primary valveftof-govrn the -supply of airto the chamber-5, andits exhaust therefrom. Over,

When the valve. isin open" position, the skirt member 10rests1flat upon the seating strip 7,

which latter supports the valve withthe member 9 in: the chamber- 0f the wind chest, andunderthe associated pipe opening inthe' basemember 8 thereof resting on the ini ward ly' projecting or overhanging portion ofitheseatingstrip within the circunifen ence of the chamber fi', and with the he'ad sound board. A retaining piecell' is disposed? ontop of the -seatin'g' strip 7, andjis' ap'er tured and shaped to-accommodate the base member Sand-the skirt 10 of thevalve. 1 The I aperture in the retaining pieceis adapted to receive'the base member*8 loosely so as to :-:permit its free movement upwardly" and 7 downwardly between the Q chamber 5 1 and the chamber' of/ the Wind FcheStJ At its undersidethe': retaining piece is countersunk' to provide a receiving space' 11 for the accommodation of the proje'cting por tion of: the skirt 10,- and intermediate the;
